Streptavidin and avidin are used ubiquitously because of the remarkable affinity of their biotin binding, but they are tetramers, which disrupts many of their applications. Making either protein ...

The cost of making a Phycoerythrin conjugated tetramer is $800. The most expensive reagents are the biotin ligase (BirA from Avidity, LLC) and the PE-conjugated streptavidin (Prozyme). On occasion, it ...

Adsorbing biotin on solid surfaces and assembling avidin makes it possible to attach active ligands to the biosensor surface, thereby identifying target species in the sample and increasing the ...

Intravenous avidin reverses the anti-Factor Xa activity of idrabiotaparinux. The researchers analyzed reversal of Factor Xa in 41 of these patients; 23 assigned to avidin.

Each tetramer is tested for the level of biotinylation. ELISA using anti b2-microglobulin antibodies specific for properly folded MHC I. Please direct ordering status inquiries or technical questions ...

All stainings are carried out at 4°C. Sometimes, higher intensity tetramer stains are obtained if incubated at room temperature or above, but some surface markers — particularly CD62L— are sensitive ...
